Hello all! I bought a 1998 Jeep Grand Cherokee Laredo about 3-4 months ago. One problem i have is that the heat wont switch from the floor. I've heard the motor that does this is called the mode actuator, which moves a flap to direct air to different ducts, etc. I've checked all vacuum line that i could see, nothing. It is quite hard to work on as everything is literally jammed under the dash. It is also quite dangerous as I cannot defrost my windshield in the winter. I get a tiiiiiny bit of heat up to the defroster, but not a lot. Heat works very well, but cannot switch from floor. Cant even hear the little hiss that you get on other cars when you switch. I just have the basic 3 knob fan speed, directional flow, and temp knobs, as well as an A/C button. Let me know what you guys come up with.
Thanks, Tanner
